A reviewer of the Speed-E Tuner says, “I was pleasantly surprised at how easy it was to use… It's small, lightweight and easily fits in your pocket! It's a keychain and has the ability to accommodate many keys, and the display is easy to read. I recommend this tuner to any guitarist! It worked great on my bass, too!"
